Hi, all!

I understand that this is not the right place to post this, hence, I request admins to move this post to a more appropriate forum.

Peace.

I am trying to learn how Metamod plugins work, so I compiled the stub_mm plugin with MinGW using the following commands.

gcc -D_WIN32 -IE:\hlsdk\common -IE:\hlsdk\dlls -IE:\hlsdk\engine -IE:\hlsdk\pm_shared -IE:\metamod -IE:\stub_plugin -O0 -g3 -Wall -c -fmessage-length=0 -oh_export.o ..\h_export.cpp
gcc -D_WIN32 -IE:\hlsdk\common -IE:\hlsdk\dlls -IE:\hlsdk\engine -IE:\hlsdk\pm_shared -IE:\metamod -IE:\stub_plugin -O0 -g3 -Wall -c -fmessage-length=0 -ometa_api.o ..\meta_api.cpp
gcc -D_WIN32 -IE:\hlsdk\common -IE:\hlsdk\dlls -IE:\hlsdk\engine -IE:\hlsdk\pm_shared -IE:\metamod -IE:\stub_plugin -O0 -g3 -Wall -c -fmessage-length=0 -odllapi.o ..\dllapi.cpp
gcc -D_WIN32 -IE:\hlsdk\common -IE:\hlsdk\dlls -IE:\hlsdk\engine -IE:\hlsdk\pm_shared -IE:\metamod -IE:\stub_plugin -O0 -g3 -Wall -c -fmessage-length=0 -osdk_util.o ..\sdk_util.cpp
gcc -D_WIN32 -IE:\hlsdk\common -IE:\hlsdk\dlls -IE:\hlsdk\engine -IE:\hlsdk\pm_shared -IE:\metamod -IE:\stub_plugin -O0 -g3 -Wall -c -fmessage-length=0 -oengine_api.o ..\engine_api.cpp

And

gcc -shared -oamx4j.dll sdk_util.o meta_api.o h_export.o engine_api.o dllapi.o

To generate the DLL.

The DLL file is being generated (size 1661KB) without any error, but Metamod cannot find the necessary functions...

These are the logs from Metamod:

PHP Code:

Then I used Eclipse's Object Browser to check the .o files and found out that the functions are there.

Let's hope I find reasonable answers and solution to my problem

Try to add -Wl,--kill-at here.

Got it to work.

Strange, but the IDE was causing issues here...
Now I made a script that compiles + deploys the DLL to the game. Thanks
